Mitigation checklist
- To mitigate this issue, ensure sticky-directory symlink protections are enabled on your system. This can be done immediately by running `sysctl -w fs.protected_symlinks=1`. To make this change persistent across reboots, create or modify a file in `/etc/sysctl.d/` (e.g., `/etc/sysctl.d/99-sysctl.conf`) with the content `fs.protected_symlinks=1` and then run `sysctl --system`. Additionally, avoid running the `sblim-cmpi-base` provider registration scripts from shared multi-user systems where untrusted users can create symlinks in `/tmp` or `/var/tmp`. If manual execution of the script is necessary, prefer using a private, root-owned temporary directory.
